Close Scottish bank set up in US financial centre (6)
I believe the answer is:
nearby
'close' is the definition.
(similar in meaning)
'scottish bank set up in us financial centre' is the wordplay.
'scottish bank' becomes 'brae' (Scottish term for a bank or hillside).
'set up' says the letters should be written in reverse.
'in' indicates putting letters inside.
'us financial centre' becomes 'NY' (New York).
'brae' reversed gives 'earb'.
'earb' put into 'ny' is 'NEARBY'.
(Other definitions for nearby that I've seen before include "Around the corner" , "Locally" , "Local" , "Adjacent" , "Close at hand, not far away" .)
